Product details
Overview
BZT52C2V4T-7 from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 2.4 V, ±8.3% tolerance (2.2–2.6 V), 300 mW power dissipation, and SOD523 package. It operates across –55 °C to +150 °C and delivers stable voltage regulation in low-voltage biasing and reference circuits for portable power management.
For engineers reviewing the BZT52C2V4T-7 datasheet, BZT52C2V4T-7 pinout, BZT52C2V4T-7 application, or BZT52C2V4T-7 equivalent, key selection criteria include zener voltage accuracy at 5 mA test current, low dynamic impedance (≤100 Ω at 1 kHz), reverse leakage ≤50 µA at 1.0 V, and thermal resistance of 417 °C/W for compact PCB designs.
Technical Context
This Zener diode functions as a precision shunt voltage reference in low-power analog and digital subsystems. Its 2.4 V breakdown is specified at IZT = 5 mA, with temperature coefficient near 0 mV/°C - enabling minimal drift over industrial temperature range.
The device uses alloy-42 leadframe with matte tin annealed terminals, supports JEDEC-compliant reflow, and meets Level 1 moisture sensitivity. Its SOD523 footprint (1.25 mm × 0.85 mm) enables high-density placement while maintaining 300 mW dissipation on standard FR-4 with 2 oz copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.4 V nominal, 2.2–2.6 V range at 5 mA - ensures tight regulation for 2.5 V rail monitoring and LDO feedback networks. |
| Power Dissipation (PD) | 300 mW - supports continuous operation in space-constrained consumer and automotive body electronics without forced cooling. |
| Zener Impedance (ZZT) | ≤100 Ω at 1 kHz - maintains low AC impedance for noise-sensitive reference paths in ADC biasing and sensor excitation. |
| Reverse Leakage (IR) | ≤50 µA at VR = 1.0 V - minimizes quiescent current draw in battery-powered voltage detection circuits. |
| Thermal Resistance (RθJA) | 417 °C/W - defines junction-to-ambient rise under 300 mW load on standard PCB; critical for thermal margin in sealed enclosures. |
| Operating Temperature | –55 °C to +150 °C - qualified for under-hood automotive modules and industrial control terminals without derating. |
Pinout & Package
Package: SOD523 - ultra-compact surface-mount plastic package (1.25 mm × 0.85 mm × 0.60 mm height), cathode indicated by band marking, compatible with automated pick-and-place and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; establishes reference polarity for shunt regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Zener voltage 2.4 V, but rated at 225 mW PD and higher ZZT (≤150 Ω); SOD-323 package (larger footprint). | Limited to lower-power biasing where thermal margin is less constrained; not recommended for 300 mW sustained loads. | Select when legacy SOD-323 footprint compatibility is required and power demand stays below 225 mW. |
| BZX84-C2V4 | Same 2.4 V rating but SOT-23 package (3.0 mm × 1.4 mm); higher PD (350 mW), but RθJA = 300 °C/W - requires larger copper area. | Better thermal handling in open-board industrial designs; incompatible with ultra-dense layouts due to size. | Prefer for applications needing higher power headroom and where board space permits SOT-23 placement. |
Compared with MMBZ5221BS-7-F and BZX84-C2V4, BZT52C2V4T-7 uniquely balances ultra-compact SOD523 size, 300 mW capability, and low-impedance regulation - making it optimal for next-generation space- and power-constrained embedded systems.

FAQ
What is the maximum reverse voltage (VR) at which leakage remains ≤50 µA?
The BZT52C2V4T-7 exhibits ≤50 µA reverse leakage at VR = 1.0 V, as specified in the Electrical Characteristics table. At VR = 2.0 V, leakage rises to ≤150 µA - confirming its suitability only for low-voltage clamping, not high-VR transient suppression.
Is this part qualified for automotive use per AEC-Q200?
Yes - the BZT52C2V4T-7 is qualified to AEC-Q200 standards for passive components and manufactured in IATF 16949-certified facilities. While the base part number lacks a Q-suffix, its qualification is documented in Diodes' automotive product definitions and applies to all BZT52C-series devices unless otherwise noted.
Can BZT52C2V4T-7 replace BZT52C2V0T in a 2.0 V reference circuit?
No - BZT52C2V4T-7 has a nominal zener voltage of 2.4 V (2.2–2.6 V range), while BZT52C2V0T is rated at 2.0 V (1.91–2.09 V). Substituting them would shift reference voltage by >200 mV, violating tolerance requirements in precision feedback loops and ADC references.
What is the thermal derating behavior above +25 °C ambient?
Per Figure 1 in DS30502, power dissipation linearly derates from 300 mW at +25 °C to zero at +150 °C, yielding a slope of –2.5 mW/°C. At +85 °C ambient, maximum allowable PD is 150 mW - requiring design verification of junction temperature using RθJA = 417 °C/W.
